“My husband and I had just started dating and he was like, ‘Hey, I have to run something by you. I always told myself that my first boy would be named Ace, so I just want to make sure if this all works out, you’d be okay with Ace,’” Finch, 32, tells PEOPLE during a recent visit to the office.

“I was like, ‘Where did that come from?!’ In some ways it was super cute because he was already thinking down the road.”

An instant fan of Daigle’s choice, the couple were delighted to discover their first child would indeed be a baby boy. “Us both being pitchers, from [his] standpoint, Ace is the best of everything,” Finch says.

And when she learned they would be welcoming a second son a few years later, the proud parents turned to another all-time favorite.

“We liked Diesel when I was pregnant with Ace. We knew we liked those two names, but obviously our first was going to be Ace,” she recalls. “So we were like, ‘All right, he’s going to be Diesel.’”

The final decision on what they will be calling their daughter, however, has not been so easy. With “a couple” possibilities in mind, Finch reveals she is leaning toward the more traditional route the third time around.

“Everyone is expecting something crazy and outrageous with having Ace and Diesel, but we’re not sure,” she explains. “[One option's] a really sweet Southern name that we might end up with. That’s kind of in the lead right now, but we haven’t decided completely yet.”
